丹巴地區位處於四川盆地北側松潘甘孜造山帶內,西側為鮮水河斷層,東南側為龍門山斷層。區域構造顯示為長約100公里寬約40公里呈西北走向的複背斜構造,背斜軸部為西藏東緣變質度最高的區域,為古生代且變質程度達混合岩、矽線石-藍晶石相的變質岩相,最高變質溫度約600-700度之間,顯示總剝蝕量約20-23公里之間,變質度向背斜兩翼漸減,主要變質作用發生於中生代,其後緩慢剝蝕抬升。
印度板塊與歐亞板塊在50Ma開始碰撞,為分析新生代的構造影響,我們利用鋯石與磷灰石核飛跡定年並結合先前的黑雲母Ar-Ar與Rb-Sr定年,分析新生代構造運動影響。結果顯示在複背斜軸部鋯石核飛跡年代14-16Ma,在軸部兩側鋯石核飛跡年代約24-25Ma。磷灰石年代顯示軸部約在5-7Ma,東翼漸增至12Ma。由背斜軸部到翼部黑雲母Ar-Ar定年顯示約50 Ma,而黑雲母Rb-Sr年代近30Ma,顯示在軸部新生代總剝蝕量約11公里,而中生代總剝蝕量約9-12公里之間。
新生代的剝蝕速率在25Ma之後逐漸加速並伴隨背斜的成長,約10-11Ma後剝蝕速率加速為約0.55mm/yr,最後階段的加速可能與龍門山斷層活動有關。
